OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 620,910, dated March 14, 1899. Application filed October 13, 1897. smart. 655,046. (No model.)

T0 at whom it may concern:

Be it knownthat I, FRANK P. GLAZIER, a citizen of the United States, residing at Ohelsea, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to the construction of an oil-stove of that type in which the vapor from the wick or burner is mixed with air to burn with a blue flame.

Theinvention consists in the following particulars: first, in the construction of the chimney or top and the means for adjusting the combustion-chamber in relation to the wick; second, the construction of this chimney or top whereby the heat of the chimney is prevented from being imparted to the body or fount of the stove by convection; third, in the construction of a centering device for the combustion-chamber around the wick and in the construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure l is aside elevation of a stove embodying my invention. Fig. 2 is a vertical central section through the burner thereof, and Fig. 3 is a perspective View of the upper part of the burner or wicktube.

A is the fount, supported on the base B and having the top ring 0, the two being secured together in any suitable manner, as by bolts D.

E is a central wick-tube passing'through the fount, as is usual in Argand burners. The upper end of the wick-tube is preferably spanned by a perforated diaphragm F. This diaphragm engages under a shoulder G,

formed by flaring the inner wall of the wicktube, as is usual in such vapor-burners, and it is secured in this position by means of a spider H, engaging on the top of the Wicktube and bolt-ed or otherwise secured to the diaphragm, as plainly shown in Fig. 2. This spider is formed with the inclined arms I, which act as guides to center the combustionchamber upon the burner or wick-tube. The combustion-chamber J is formed by the perforated tubes or b, resting on the inner and outer edges of the burner, as plainly shown in Fig. 2. These tubes are secured together and to the drum K by means of the crossing rods L, which rods at their ends engage in in-' clined slots M in the drum K. One or more of these crossing rods are provided at their ends with knobs L, and by taking hold of one and causing it to ride up the incline the tubes at b, which form the combustion-chamber, are lifted up clear of the wick, so that while the flame is not burning the chimney can be kept out of contact with the oil from the wick, which otherwise would create un pleasant odors on relighting.

The combustion-chamber and the drum form what I call the chimney or top. The drum is provided at its lower edge preferably with a ring-casting O, by means of which it is hinged to the ring 0, so that the whole. top or chimney may be turned back upon its hinges to expose the wick for trimming, &c.

I provide an annular opening P between the drum and the top of ring 0 and form one or more projections or feet Q, which (in addi tion to the hinge) support the drum on the ring 0, so that the least possible contactingsurface is had between the drum and ring G. This not only provides a free air circulation into the drum, but also prevents the heat of the drum or chimney from being transmitted by convection to the body or fount of the stove. The ring 0 is likewise provided with slots S to, provide for air-currents, which tend additionally to prevent the heating of the fount.

Around the lower part of the combustionchamberis aring T, supported on a perforated cylinder U. This guards the flame from direct drafts of air which might come in through the perforated ring S or the slot P.

What I claim as my invention is 1. In a vapor-burning oil-stove, the combination of the burner, an air-mixing combustion-chamber over the burner, and a drum inclosing the combustion-chamber, said combustion-chamber being so connected with the drum that it has a movement relative thereto by which it may be adjusted independently of the drum.

- 2. In a vapor-burning oil-stove, the combination of a burner, an air-mixing combustionchamber over said burner, a drum inclosing the combustion chamber, said combustion combustion-chamber over the burner, a drum inclosing the same, cross-rods movably connecting these parts, and inclined slots in the drum into which the ends of these rods engage, whereby a partial rotation of the rods will lift the combustion-chamber free from the wick.

5. The combination with an Argand burner,

of a combustion-chamber above the same having perforated walls, a perforated cylinderU surrounding the burner below the combustion-chamber, and an imperforate ring inter mediate the upper part of the cylinder U and lower part of the combustion-chamber.

6. In a vapor-burner, the combination of a wick-tube, a perforated diaphragm closing the top of the wick-tube, a spider having inclined sides engaging the top of the Wick-tube and secured to said diaphragm, and a combustion-chamber adapted to be guided by said spider.

7. In an Argand Vapor-burner, the wicktube having its inner wall flanged inwardly at the top, a perforated diaphragm engaging the under side of this flange and a spider engaging the top of the wick-tube into which the diaphragm is secured.

8. In an Argand vapor-burner, the combination with a wick-tube, a combustion-chamber above the same, and a drum surrounding the latter, of a ring 0 upon which the drum .is supported having apertures S, and a perforated cylinder U below the lower part of the combustion-chamber within the ring 0, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses,

F. P. GLAZIER.
